About S11.01

S11.01 is the ICD-10-CM diagnosis code for open wound of larynx. It belongs to category S11 (open wound of neck), block S10-S19 (injuries to the neck) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within S11.0 (open wound of larynx and trachea), S11.01 is specifically for open wound of larynx. Related codes cover trachea (S11.02) and vocal cord (S11.03).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

The conditions in its Excludes2 note aren't part of S11.01, but may be coded alongside it if the patient has both: open wound of vocal cord (S11.03).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
